If the pesticides were banned, how fast would their population be replenished? Or do they persist, akin to CFCs?

#12This seems like part of the insect apocalypse story, and bee colony collapse disorder. All probably caused by overuse of insecticides. Note that if we don't find a way to correct this, it can be catastrophic on a timescale that makes the most alarmist climate change predictions seem like nothing. There must be some percentage of normal insect population density below which population of frogs and birds and what not w…
In fact the researchers measuring the loss of insect biomass in puerto rico rainforests attributed it primarily to climate change since the other factors do not apply there.

For those who aren’t aware what they’re referring to by insect apocalypse, a story came out a few days ago about some seemingly very important insect research:

#14Any news about the pesticides killing off bees and butterflies? Have any been banned yet?

#17I planted milkweed in my front yard. These plants don't come cheap, between 10-20$ at the nursery for a young plant. I never was able to grow them from seed. Anyways, the plants did attract a few monarchs late summer/early fall. I counted two. I planted nine total. I got a code violation warning last month for not mowing my front yard and having overgrown "landscape weeds".
The plot is in a major migration route and this is the first year I'll be actively be supporting Monarchs, other than planting my usual garden herbs. They seem to like carrots and parsley. You have inspired me, thank you, trgn.

I planted milkweed seed about 3 years ago. Had my first plant that sprouted and survived in the spot I planted just this past summer. Give it some time, you never know. Some seeds have to go through a freeze/thaw cycle or two to sprout properly.
